7.7.1

Free assignment of D numbers, cutting edge numbers (CE address)

D number
The D numbers can be used as contour numbers. You can also address the number of the
cutting edge via the address CE. You can use the system variable $TC_DPCE to describe the
cutting edge number.
Default: compensation no. == tool edge no.
Machine data are used to define the maximum number of D numbers (cutting edge numbers)
and the maximum number of cutting edges per tool ( → machinery construction OEM). The
following commands are only practical if the maximum cutting edge number (MD18105) was
specified to be greater than the number of cutting edges per tool (MD18106). See machine
manufacturer's specifications.
Note
In addition to relative D number allocation, the D numbers can also be assigned as "flat" or
"absolute" D numbers (1-32000) without a reference to a T number (within the "Flat D
number structure" function).
